C extension compilation failed while using PG 17.2 on mac m1

[Lakshmi Narayana Velayudam]

Hello, while compiling my c extension with PG 17,2 I am getting

postgresql-17.2/pgsql/include/server/port/pg_iovec.h:93:10: error: call to
undeclared function 'pwritev'; ISO C99 and later do not support implicit
function declarations [-Wimplicit-function-declaration]

   93 |                 return pwritev(fd, iov, iovcnt, offset);


I am not using pg_iovec.h or pwrite/pread related functions. My extension
compiles fine without any issues on PG 14.3

*PG compilation commands:*
./configure --prefix=$PWD/pgsql --enable-cassert --enable-debug
CFLAGS="-ggdb -fno-omit-frame-pointer -O0" --without-icu
make clean
make -j
make install -j

*Mac OS:* 15.1.1

Please let me know if you need any other information.

Thanks & Regards,
Narayana
